Opposite guide part 3e is the face substantially vertical with left and right directions, relative to guide part 3c, in the lateral direction across
Interarea 3z is opposed.Opposite guide part 3e has the second locking hole 3f set on front end side, set on the protrusion 3g of upper avris.As after
It states, protrusion 3g, which improves the efficiency that whether visual confirmation is normally assembled when guide part 3c is assembled in cover 4, (to be realized and make
For the function of the second label).In addition, protector 3 is for example formed by metal.
[cover 4]
Fig. 2 (b) is the perspective view for illustrating cover 4, and Fig. 3 is the main view of cover 4.In Fig. 3, before being towards the direction in front of paper
Direction.
Cover 4 has the first pawl 4b engaged when being assembled in protector 3 with the first locking hole 3b, is equipped with and is inserted into for guide part 3c
Opening 4c right side 4d, for opposite guide part 3e insertion opening 4e, can assemble power supply line (not shown) line install
Portion 4h, terminal press section 4j and while being assembled in protector 3 rear surface 4z opposed with interarea 3z.Cover 4 with formed opening 4c,
The mode of 4e is respectively provided with the region of tubular.The second pawl 4f locking with the second locking hole 3f is equipped in opening 4e.Cover 4 is by energy
Enough flexible deformations or flexible material, such as synthetic resin are formed.
Opening 4c, 4e are tubulars, therefore are to separate space with the inside of cover 4, are normally installed on protector in cover 4
In the state of 3, inhibit to reach inside the water droplet intrusion cover 4 of opening 4c, 4e.
Line mounting portion 4h is set to the lower side of cover 4.Pass through the lower end upwards made of bending by power supply line engaging in cover 4
Region between bending section 4h1 and interarea 4z, so as to inhibit falling off for power supply line.Line mounting portion 4h and the outside of cover 4 connect
It is logical, but be open downward, therefore be able to suppress water droplet immersion.
Terminal press section 4j be in mounting cup 4, can be in contact with or close to the protrusion for the terminal being connect with glass end 2.
In the case where cover 4 is resin etc., in mounting cup 4, when operator presses interarea 4z forwards, 4 deformation of cover, terminal is pressed
Splenium 4j contact terminal.As a result, for example in the non-normal mounting of terminal in the case where glass end 2, it can utilize operator's
Pressing force is installed.
[assembly of protector 3 and cover 4]
Fig. 4 is the perspective view of 4 assembled state of cover, and Fig. 5 is the cross-sectional view of 4 intercalation state of cover, in Fig. 6 (a) be from right direction,
It (b) is the figure that the cover 4 of 4 half intercalation states is covered from left direction, it is from left direction that (a), which is from right direction, (b), in Fig. 7
Cover the figure of the cover 4 of 4 intercalation states.
Protector 3 and cover 4 are for example assembled and colliding and being inserted into the direction of dotted arrow shown in FIG. 1.Once group
Protector 3 and cover 4 are filled, then forms the space by the encirclements such as interarea 3z and rear surface 4z, it is whole that electric component, glass can be stored
The receiving room at end 2.
As assembling, specifically, firstly, when encountering cover 4, than the in the first pawl 4b and the second pawl 4f contact top plate 3a
The region in direction rearward than the second locking hole 3f in the region in direction and opposite guide part 3e rearward one locking hole 3b.Due to it
Contact, generate certain degree because friction caused by resistance.In the case where cover 4 is formed by the material for capableing of flexible deformation,
The resistance is bigger.That is, the operator of mounting cup 4 can easily feel the case where pawl 4b, 4f touch protector 3.
When being further hit against with the power for being greater than the resistance from this, the first pawl 4b and the second pawl 4f enter the first locking hole 3b
And the second locking hole 3f, so that resistance weakens, substantially simultaneously, they engage.By 4 normal mounting of cover in protector 3 state,
In the present embodiment, the first pawl 4b is sticked in the first locking hole 3b (referring to Fig. 5 etc.) and the second pawl 4f is sticked in the second locking hole
The state of 3f is known as assembled state.In addition, although cover 4 is encountered protector 3, the two not by the state of normal mounting,
In the present embodiment, the one side or both sides of these pawls 4b, 4f are not known as half assembled state with hole 3b, 3f state engaged respectively.
Under assembled state, guide part 3c is exposed to cover 4 from opening 4c, and a part of opposite guide part 3e is exposed from opening 4e
In cover 4.Particularly, label 3d exposes a part from opening 4c, protrusion 3g from opening 4e respectively, preferably as Fig. 7 (a), (b) are illustrated
All expose on ground.
Under half assembled state, label 3d from opening 4c, protrusion 3g from opening 4e expose the range different from assembled state (
In the present embodiment, the range fewer than assembled state), or label 3d and/or protrusion 3g Hide All (cannot see that).In this reality
It applies in example, in the assembled condition, the label 3d for being set as circular hole all exposes (referring to Fig. 7 (a) etc.), in half assembled state
Under, expose a part (referring to Fig. 6 (a) etc.).In addition, in the assembled condition, exposing protrusion 3g (referring to Fig. 7 (b) etc.), being filled half
With under state, Hide All (referring to Fig. 6 (b) etc.).From the viewpoint of manufacturing tolerance (machining accuracy), 3d, protrusion 3g are marked
It is preferred that being set as traversing 0.1mm or more, preferably 0.2mm or more in the longitudinal direction.From the viewpoint of operator is easy to range estimation,
More bigger, more limited, for example, preferably in any direction on be 2mm or more.
Here, such as Fig. 6 (a) is illustratively, the anteroposterior dimension of the barrel of opening 4c is formed due to being set to right side 4d
Notch 4da and it is shorter than the anteroposterior dimension of right side 4d.Therefore, even if making guide part 3c and marking anteroposterior dimension and the right side of 3d
The anteroposterior dimension of face 4d is roughly the same or shorter, and in assembly, guide part 3c, label 3d can also be exposed to cover 4.As a result,
Guide part 3c, label 3d will not project to direction rearward than cover 4 and (be accommodated in the rear end than cover 4 by front side.), and can be from a left side
Right direction (in the present embodiment, right direction) is visual.
In addition, there are operators to judge (misunderstanding) for the state before assembled state normally to be filled when installation
With the case where.Particularly, it when that will cover 4 and be formed by synthetic resin etc., can be constructed as follows: with collision, pawl 4b, 4f's
Deflection is cumulative, keeps the resistance because of caused by friction cumulative.Thus, it is possible to keep the installation condition of cover 4 secured, on the other hand, deposit
In following problems: being easy to realize half assembled state as the state before assembled state, operator is easier to misread.Therefore, make
With pawl 4b, 4f for being set to cover 4 of resinousness, make to firmly install, and using set on guide part 3c, the 3e contacted with pawl 4b, 4f
Label 3d, 3f can be realized preferred installation so as to inhibit operator that half assembled state is mistakenly considered assembled state
Construction.
Fig. 8 is the perspective view of the state of refrigerator assembling.According to the present embodiment, mesh can be distinguished from left and right directions either direction
Sighting target remembers 3d or protrusion 3g, therefore even if compressor 1 is assembled in the equipment such as refrigerator 10, also easily can visually cover 4 dress
With state.Thus, for example, also being easily determined even if becoming half insert state because of vibration in compressor operation.
[other way etc.]
In addition, the color of the part of exposing can also be made into as label 3d and be easy visual red, yellow etc..By
This, can be made into the label being easily worked with cheap price.
In addition, the space for the electric parts (not shown) for storing current flowing is made into the sky separated be open 4c, 4e by cover 4
Between.Thereby, it is possible to prevent water, dust, rubbish, worm etc. from opening 4c, 4e intrusion, it is made into the electric component protection of high reliablity
Cover.The assembling of cover 4 is carried out, using pawl without screw etc. so as to effectively inhibit in the immersions such as water droplet cover 4.
In addition, in the present embodiment, in order to improve visuality, judged using label 3d, protrusion 3g, but can also be with
It is configured to only judge by capableing of the front end of the visual front end of guide part 3c, opposite guide part 3e.Specifically, can will open
The notch of mouthful 4c is designed as, in the assembled condition, can be from the front end of the opening visual guide part 3c of 4c, and in half assembled state
Under, cannot visual guide part 3c front end.
Both in addition, in the present embodiment, assembled in such a way that cover 4 surrounds protector 3.That is, with the side of cover 4, upper table
The mode that face is located at the outside of top plate 3a, guide part 3c and opposite guide part 3e assembles.Moreover, hole 3b is set to protector 3
Side, pawl 4b are set to the side of cover 4.Hole is located inside as a result, therefore is able to suppress water droplet and enters inside via hole.
In addition, in the present embodiment, for protector 3, the first hole 3b, the second hole 3f and label 3d are respectively arranged on not
Same direction (in the present embodiment, upper respectively, left and right side).That is, label 3d is in the position separated respectively with hole 3b, 3f, because
This, even if being able to suppress becomes exposing shape identical with assembled state in the case where half assembled state that any one does not engage
State.In contrast, such as protrusion 3g, when close to the position setting flag in arbitrary hole, if generating other than the hole
Hole engaging abnormal state of affairs half assembled state, then the exposing range marked is similar to assembled state, exists and is difficult to area
Other problem.It, can relatively each hole ground setting flag it is preferred, therefore, that such as the present embodiment.In the present embodiment
In, the label with quantity identical as the number in hole, but the number marked can also be more.
[other combined methods]
Construction based on the present embodiment, above-mentioned method can also be replaced and use the following method by covering 4 assembling.
Opposite guide part 3e and the second hole 3f is set to the left end of protector 3, and the first hole 3b of top surface 3a is set to left and right directions
End other than position (for example, center side).Therefore, firstly, the second pawl 4f of cover 4 is made to be sticked in the second hole 3f, then with
The the second pawl 4f and the second hole 3f of engaging are axis rotation, to the close first pawl 4b of the first hole 3b.Then, apply pressing forwards
Power makes the first pawl 4b be sticked in the first hole 3b.
It,, can be with smaller using lever principle using the second pawl 4f and the second hole 3f as axis when being assembled in this wise
Power carry out the process for making the first pawl 4b be sticked in the first hole 3b.This assembling operation is because guide part 3e in opposite is located at right and left
To end, therefore it is easy to ensure that rotary shaft, so being easy to carry out.
